BACKGROUND Field of the Disclosure

This disclosure relates generally to information handling systems and more particularly to utilizing thermal profiles associated with workload executing on information handling systems.

Description of the Related Art

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

SUMMARY

In one or more embodiments, one or more systems, one or more methods, and/or one or more processes may execute a first workload on multiple information handling systems; may determine first multiple thermal attribute values associated with the multiple information handling systems with respect to a period of time as the multiple information handling systems execute the first workload; may determine multiple variance ranges respectively associated with the multiple thermal attributes; may execute a second workload on the multiple information handling systems; may periodically determine second multiple thermal attribute values associated with the multiple information handling systems as the multiple information handling systems execute the second workload; may determine that a thermal attribute value of the second multiple thermal attribute values exceeds a respective variance range of the multiple variance ranges as a first information handling system of the multiple information handling systems execute the second workload; in response to determining that the thermal attribute value of the second multiple thermal attribute values exceeds the respective variance range, may generate an alert based at least on the thermal attribute value exceeding the respective variance range; and in response to the alert, may transfer at least a portion of the second workload from the first information handling system to a second information handling system of the multiple information handling systems. In one or more embodiments, the one or more systems, the one or more methods, and/or the one or more processes may further, in response to the alert, provide a message to a user indicating that the thermal attribute value of the second multiple thermal attribute values exceeds the respective variance range.

In one or more embodiments, transferring the at least the portion of the second workload from the first information handling system to the second information handling system may include transferring the second workload from the first information handling system to the second information handling system. For example, the second workload may include a virtual machine. In one or more embodiments, the thermal attribute value of the second multiple thermal attribute values may include a fan speed of a fan of the first information handling system, a temperature value of a processor of the first information handling system, or a ratio of an inlet temperature value to an outlet temperature value associated with the first information handling system. For example, the thermal attribute value of the second multiple thermal attribute values may include the ratio of the inlet temperature value to the outlet temperature value associated with the first information handling system. For instance, the first information handling system may include multiple sensors, in which a first sensor of the multiple sensors is located at or near an air inlet of the first information handling system and is configured to determine the inlet temperature value and in which a second sensor of the multiple sensors is located at or near an air outlet of the first information handling system and is configured to determine the outlet temperature value.

DETAILED DESCRIPTION

In the following description, details are set forth by way of example to facilitate discussion of the disclosed subject matter. It should be apparent to a person of ordinary skill in the field, however, that the disclosed embodiments are examples and not exhaustive of all possible embodiments.

As used herein, a reference numeral refers to a class or type of entity, and any letter following such reference numeral refers to a specific instance of a particular entity of that class or type. Thus, for example, a hypothetical entity referenced by ‘12A’ may refer to a particular instance of a particular class/type, and the reference ‘12’ may refer to a collection of instances belonging to that particular class/type or any one instance of that class/type in general.

In one or more embodiments, a datacenter may remove heat from information handling systems. For example, a cooling system associated with the datacenter may be utilized to remove heat from the information handling systems and/or to cool the information handling systems. In one or more embodiments, an information handling system may include one or more sensors. For example, the one or more sensors may be utilized in determining one or more temperature values at one or more physical locations within the information handling system. In one or more embodiments, one or more alerts may be generated based at least on the one or more temperature values. For example, the one or more alerts may be generated based at least on one or more deviations from one or more temperature ranges. For instance, the one or more alerts may be provided to one or more applications, which may perform one or more actions based at least on the one or more alerts.

In one or more embodiments, the cooling system associated with the datacenter may provide cooling in response to the one or more alerts. In one example, the cooling system may increase a volumetric airflow rate at or near an information handling system associated with the one or more alerts. In another example, the cooling system may lower a temperature of air at or near an information handling system associated with the one or more alerts. In one or more embodiments, an application executed by the information handling system may cause the information handling system to generate heat. For example, a first application executed by the information handling system may cause the information handling system to generate a first amount of heat, and a second application executed by the information handling system may cause the information handling system to generate a second amount of heat. For instance, the first amount of heat may be greater than the second amount of heat.

In one or more embodiments, one or more systems, one or more methods, and/or one or more processes may implement thermal management of the information handling system based at least on a workload of the information handling system. For example, one or more thermal characteristics associated with the workload may be determined based at least on one or more temperature values while the workload is executed on the information handling system. For instance, a machine learning process may determine the one or more thermal characteristics associated with the workload based at least on one or more temperature values while the workload is executed on the information handling system. In one or more embodiments, the machine learning process may determine a thermal profile associated with the workload based at least on the one or more thermal characteristics associated with the workload. For example, the thermal profile associated with the workload may be deemed a golden profile for that workload.

In one or more embodiments, a first information handling system may be different from a second information handling system. For example, the workload may be associated with multiple different thermal profiles based at least on executing the workload on multiple different information handling systems. In one instance, the workload may be associated with a first thermal profile when the workload is executed on a first information handling system. In another instance, the workload may be associated with a second thermal profile, different from the first thermal profile, when the workload is executed on a second information handling system, different from the first information handling system.

In one or more embodiments, a golden profile associated with a workload may be adjusted based at least on one or more characteristics associated an information handling system that may be utilized to process the workload. In one example, a first thermal profile associated with the workload may be determined based at least on the golden profile associated with the workload and one or more characteristics associated a first information handling system that may be utilized to process the workload. In another example, a second thermal profile associated with the workload may be determined based at least on the golden profile associated with the workload and one or more characteristics associated a second information handling system that may be utilized to process the workload. For instance, if at least one of the one or more characteristics associated the second information handling system is different from at least one of the one or more characteristics associated the second information handling system, the second thermal profile associated with the workload may be different from the first thermal profile associated with the workload.

In one or more embodiments, the cooling system of the datacenter may consume a portion of an entire energy consumption of the datacenter. For example, the cooling system of the datacenter may consume approximately ten percent (10%) of the entire energy consumption of the datacenter. In one or more embodiments, maintaining a thermal coefficient between hot isles and cool isles of the datacenter may be a factor in maintaining an optimal load on the cooling system associated with the datacenter, which may affect power consumption of the cooling system.

In one or more embodiments, monitoring a workload utilizing a thermal profile associated with the workload may yield a uniform resource utilization and an optimal thermal coefficient between hot isles and cool isles of the datacenter associated with a cluster of information handling systems. For example, the information handling systems may be homogeneous information handling systems. For instance, the homogeneous information handling systems may include same or similar components. In one or more embodiments, this may provide an optimal load on the cooling system. For example, the optimal load on the cooling system may optimize a carbon footprint associated with the datacenter.

In one or more embodiments, one or more thermal profiles may be updated based at least on one or more thermal behaviors of homogeneous information handling systems in a cluster that execute similar workloads. For example, the one or more thermal profiles may be updated based at least on a type of an information handling system, a configuration of the information handling system, a cluster grouping based at least on workload type, workload distribution over time, an inlet and outlet temperature value variance associated with a time period, and a volumetric of airflow rate for the time period, among others.

In one or more embodiments, the one or more thermal profiles may be iteratively updated based at least on actual deviations from initially determined values. For example, the one or more thermal profiles may be iteratively updated based at least on a percentage of information handling systems associated with a cluster deviating from the initially determined thermal profile values. For instance, a thermal profile may be iteratively updated as shown in Table 1.

TABLE 1 Inlet/outlet temperature Workload % value ratio Volumetric airflow rate Fan speed 10-70 (step by 5%) Initially from vendor Initially from vendor Initially from vendor information handling information handling information handling system statistics and system statistics and system statistics and later iterated over time later iterated over later iterated over as per actual values time as par actual time as per actual values

In one or more embodiments, a variance associated with a thermal profile may be configured. For example, a user (e.g., an administrator) may configure the variance associated with the thermal profile. In one or more embodiments, the thermal profile may include multiple attributes. For example, the multiple attributes may include a workload over time, ratios of inlet temperature values and outlet temperature values, and fan speeds, among others.

In one or more embodiments, the variance associated with the thermal profile may include multiple tolerances respectively associated with the multiple attributes. For example, the multiple tolerances may include a first tolerance associated with the workload over time, a second tolerance associated with the ratios of inlet temperature values and outlet temperature values, and a third tolerance associated with the fan speeds. For instance, as an information handling system processes the workload associated with the thermal profile, it may be permitted if: the workload over time is within the first tolerance (e.g., plus or minus the first tolerance of the workload over time of the golden profile), the ratios of inlet temperature values and outlet temperature values are within the second tolerance (e.g., plus or minus the second tolerance of the ratios of inlet temperature values and outlet temperature values of the golden profile), and the fan speeds are within the third tolerance (e.g., plus or minus the third tolerance of the fan speeds of the golden profile).

In one or more embodiments, if an attribute of the thermal profile is determined not to be within an associated tolerance, an alert may be generated. For example, receiving the alert may mitigate or eliminate an increase in a cooling power requirement for the information handling system processing the workload. For instance, a damaged or malfunctioning fan of the information handling system may cause the alert to be generated. As an example, the fan may be repaired, serviced, or replaced rather than having additional cooling from the datacenter applied to the information handling system. As another example, a cluster manager may not provide an additional workload to the information handling system until an issue associated with the alert is addressed. For instance, that action, and other possible one or more actions, may assist and/or aid in maintaining a thermal compliance for the cluster of information handling systems. In one or more embodiments, if no issue is determined to be associated with the alert, a variance may be modified. For example, if no issue is determined to be associated with the alert, the user (e.g., the administrator) may adjust the variance. In one or more embodiments, an original equipment manufacturer (OEM) may publish one or more policies associated with volumetric airflow rates and thermal profiles for information handling systems associated with a type of workload, among others. For example, this may be further enhanced with real time data, where in an initial golden reference may be replaced with measured reference data.

In one or more embodiments, a management console may determine that multiple information handling systems are included in a cluster. The management console may determine inventories of the information handling systems. For example, the management console may poll respective baseboard management controllers of the information handling systems to determine inventories of the information handling systems. For example, the baseboard management controllers may provide component information associated with the respectively associated information handling systems to the management console.

In one or more embodiments, the management console may determine inlet temperature values, outlet temperature values, fan speeds, and volumetric air flow rates at time intervals (e.g., periodic time intervals) for the respective information handling systems. For example, the baseboard management controllers may provide sensor data associated with the respectively associated information handling systems to the management console. For instance, management console may determine the inlet temperature values, the outlet temperature values, the fan speeds, and the volumetric airflow rates based at least on the sensor data from the baseboard management controllers.

In one or more embodiments, the management console may determine workloads executing on the information handling systems at the time intervals (e.g., the periodic time intervals). For example, the management console may utilize the baseboard management controllers to determine workloads executing on the information handling systems at the time intervals. For instance, the baseboard management controllers may delegate acquiring information associated with the workloads to executables, executing in an operating system environment on the respective information handling systems.

In one or more embodiments, the executables may delegate acquiring information associated with the workloads to operating systems executing on the respective information handling systems. For example, the executables may receive information associated with the respective workloads and may provide the information associated with the respective workloads to the respective baseboard management controllers, which may provide the information associated with the respective workloads to the management console.

In one or more embodiments, the management console may build and/or update one or more thermal profiles associated with the workloads. For example, the management console may build and/or update one or more thermal profiles associated with the workloads based at least on the information associated with the respective workloads and the inlet temperature values, the outlet temperature values, the fan speeds, and the volumetric airflow rates, among others. For instance, the one or more thermal profiles may be determined and/or updated as the information handling system process the workloads.

Turning now to FIGS. 3A-3D, examples of plots of attributes associated with processing workloads are illustrated, according to one or more embodiments. In one or more embodiments, multiple attributes may be associated with respective multiple axes. In one example, an axis 310A may be associated with time associated with processing a workload. In a second example, an axis 310B may be associated with a fan speed of a fan of IHS 110. For instance, a fan speed may be measured in revolutions per minute (RPM). In another example, an axis 310C may be associated with a ratio of an inlet temperature value to an outlet temperature value. In one instance, the inlet temperature value may be associated with a temperature value at or near an air inlet of IHS 110. In another instance, the outlet temperature value may be associated with a temperature value at or near an air outlet of IHS 110.

In one or more embodiments, a plot 320 may illustrate an ideal fan speed of an IHS 110 along with an ideal ratio of an inlet temperature value to an outlet temperature value of IHS 110 with respect to a first workload processed by IHS 110 over time, according to one or more embodiments. For example, plot 320 may be associated with a golden reference. For instance, the first workload processed by IHS 110 over time may be associated with the golden reference.

In one or more embodiments, when an IHS 110 processes a workload, a fan speed of a fan of IHS 110 along with a ratio of an inlet temperature value to an outlet temperature value of IHS 110 may be within an allowable variance 330. In one example, as shown in FIG. 3B, a plot 340A may illustrate a fan speed of a fan of IHS 110A along with a ratio of an inlet temperature value to an outlet temperature value of IHS 110A with respect to a second workload processed by IHS 110A over time.

For instance, plot 340B may not be within allowable variance 330 as IHS 110B processes the third workload. As shown, plot 340B may not be within allowable variance 330 during a time period 350 (e.g., an amount of time transpiring). For example, plot 340B illustrates that one or more of the fan speed of the fan of IHS 110B and the ratio of the inlet temperature value to the outlet temperature value of IHS 110B may deviate beyond allowable variance 330. For instance, the one or more of the fan speed of the fan of IHS 110B and the ratio of the inlet temperature value to the outlet temperature value of IHS 110B may deviate beyond allowable variance 330 during time period 350.

For example, plot 340C may not be within allowable variance 330 as IHS 110C processes the fourth workload. As shown, plot 340C may not be within allowable variance 330 during a time period 352 (e.g., an amount of time transpiring). For example, plot 340C illustrates that one or more of the fan speed of the fan of IHS 110C and the ratio of the inlet temperature value to the outlet temperature value of IHS 110C may deviate beyond allowable variance 330. For instance, the one or more of the fan speed of the fan of IHS 110C and the ratio of the inlet temperature value to the outlet temperature value of IHS 110C may deviate beyond allowable variance 330 during time period 352.

In one or more embodiments, a process 412 of the management console may poll inventory of managed information handling systems. For example, process 412 may poll inventory of IHSs 110A-110N. For instance, polling inventory of IHSs 110A-110N may include polling each BMC 130 of IHSs 110A-110N for inventory information associated with each IHS 110. As an example, a process 422 of a BMC 130 of an IHS 110 may provide component register information to process 412. For instance, component register information may include information associated with components of an IHS 110. In one or more embodiments, an inventory of an IHS 110 may include information associated with components of IHS 110.

In one or more embodiments, process 412 may provide the inventory information associated with each IHS 110 of IHSs 110A-110N to a process 414 of the management console. For example, process 414 may prepare an inventory of homogeneous information handling systems and components based at least on the inventory information associated with each IHS 110 of IHSs 110A-110N. For instance, the inventory of homogeneous information handling systems and components may include an inventory of at least a portion of IHSs 110A-110N.

In one or more embodiments, the at least a portion of IHSs 110A-110N may be a subset of IHSs 110A-110N. In one or more embodiments, the at least a portion of IHSs 110A-110N may be all of IHSS 110A-110N.

In one or more embodiments, a process 416 of the management console may poll inlet and outlet temperature values, fans speeds, and air flow data at a periodic interval. For example, process 416 may poll inlet and outlet temperature values, fans speeds, and air flow data at a periodic interval of each IHS 110 of the at least the portion of IHSs 110A-110N. For instance, a process 424 of a BMC 130 of each IHS 110 of the at least the portion of IHSs 110A-110N may provide sensor data to process 416. As an example, the sensor data may include inlet and outlet temperature values, fans speeds, and airflow data. An another example, the sensor data may include information utilizable by process 416 to determine inlet and outlet temperature values, fans speeds, and airflow data.

In one or more embodiments, a process 418 of the management console may poll for workloads at the periodic interval. For example, process 418 may poll a process 426 of each BMC 130 of each IHS 110 of the at least the portion of IHSs 110A-110N for workloads at the periodic interval. For instance, process 426 may delegate to an OS agent (e.g., a host OS agent) to obtain workload details. As an example, the OS agent may include instructions executable by a processor 120. For instance, the OS agent may include an APP of APPs 164-168. In one or more embodiments, the OS agent may determine hardware metrics and OS-level metrics associated with an IHS 110 that executes the OS agent.

In one or more embodiments, a process 430 of the OS agent may delegate a workload request to an OS. For example, process 430 may delegate a workload request to OS 162. In one or more embodiments, a process 434 of the OS determine the OS-level metrics associated with the workload. For example, the OS-level metrics associated with the workload may include information associated with processor and memory utilization, among others, as the workload is processed. In one or more embodiments, process 434 may provide workload data to the OS agent. For example, process 434 of the OS may provide the workload data to a process 432 of the OS agent. In one or more embodiments, the workload data may include information associated with processor and memory utilization, among others. In one or more embodiments, process 432 may provide the workload data to the BMC. For example, process 432 may provide the workload data to BMC 130.

In one or more embodiments, process 416 may provide the inlet and outlet temperature values, the fans speeds, and the air flow data associated with the at least the portion of IHSs 110A-110N to a process 420 of the management console, and process 418 may provide the workload data associated with the at least the portion of IHSs 110A-110N to process 420. For example, process 420 may dynamically build and update thermal profiles associated with the at least the portion of IHSS 110A-110N. In one or more embodiments, process 420 may perform an inference based at least on the thermal profiles associated with the at least the portion of IHSs 110A-110N. For example, process 420 may infer a potential deviation from thermal characteristics, which may trigger an alert. For instance, the alert may be associated with an obstruction in a desired airflow, an aging of thermal heat paste, etc.

In one or more embodiments, catching a deviation early may be a proactive measure to detect an increase in a cooling power requirement for an IHS 110 of the at least the portion of IHSs 110A-110N. For example, in response to the cluster manager receiving the alert, the cluster manager may perform one or more appropriate actions. In one instance, the one or more appropriate actions may include not loading an affected IHS 110 of the at least the portion of IHSS 110A-110N with an additional workload. In a second instance, the one or more appropriate actions may include transferring a workload from an affected IHS 110 of the at least the portion of IHSs 110A-110N to another IHS 110 of the at least the portion of IHSs 110A-110N, which is not affected.

In another instance, the one or more appropriate actions may include transferring a virtual machine from an affected IHS 110 of the at least the portion of IHSS 110A-110N to another IHS 110 of the at least the portion of IHSs 110A-110N, which is not affected. In one or more embodiments, after each IHS 110 of the at least the portion of IHSs 110A-110N are within a standard thermal profile, a user (e.g., an administrator) may inspect the at least the portion of IHSs 110A-110N and may adjust or readjust an allowable variance (e.g., allowable variance 330).

In one or more embodiments, a workload may include processing multiple queries received via network 190. In one example, in response to the cluster manager receiving the alert, the cluster manager may not permit an affected IHS 110 of the at least the portion of IHSs 110A-110N to respond to the multiple queries. In another example, in response to the cluster manager receiving the alert, the cluster manager may not permit an affected IHS 110 of the at least the portion of IHSs 110A-110N to respond any more queries.

Turning now to FIG. 5 , an example of a method of operating a system of information handling systems is illustrated, according to one or more embodiments. At 510, a first workload may be executed on multiple information handling systems. For example, IHSs 110A-110N may execute a first workload. For instance, the first workload may be associated with a golden profile. In one or more embodiments, a golden reference may be determined via executing the first workload on the multiple information handling systems. For example, the golden reference may be determined via executing the first workload on at least a portion of IHSs 110A-110N, which are homogenous.

At 515, first multiple thermal attribute values associated with the multiple information handling systems may be determined with respect to a period of time as the multiple information handling systems execute the first workload. For example, the first multiple thermal attribute values may be associated with the golden profile. For instance, the first multiple thermal attribute values may be plotted via plot 320 (shown in FIG. 3A). In one or more embodiments, a cluster manager may determine first multiple thermal attribute values associated with the multiple information handling systems with respect to a period of time as the multiple information handling systems execute the first workload. In one or more embodiments, baseboard management controllers (BMCs) 130 respectively associated with IHSs 110A-110N may determine first multiple thermal attribute values associated with the multiple information handling systems with respect to a period of time as the multiple information handling systems execute the first workload. For example, BMCs 130 respectively associated with IHSs 110A-110N may provide, to the cluster manager, the first multiple thermal attribute values associated with the multiple information handling systems with respect to the period of time as the multiple information handling systems execute the first workload.

At 520, multiple variance ranges respectively associated with the multiple thermal attribute values may be determined. For example, the cluster manager may determine multiple variance ranges respectively associated with the multiple thermal attribute values. In one or more embodiments, allowable variance 330 (shown in FIGS. 3A-3D) may be associated with the multiple variance ranges respectively associated with the multiple thermal attribute values. At 525, the multiple information handling systems may execute a second workload. For example, IHSs 110A-110N may execute a second workload. For instance, the at least the portion of IHSs 110A-110N, which are homogenous, may execute the second workload.

At 530, second multiple thermal attribute values associated with the multiple information handling systems may be determined as the multiple information handling systems execute the second workload. In one example, the cluster manager may periodically determine second multiple thermal attribute values associated with the multiple information handling systems as the multiple information handling systems execute the second workload. In another example, BMCs 130 respectively associated with IHSs 110A-110N may periodically determine second multiple thermal attribute values associated with the multiple information handling systems as the multiple information handling systems execute the second workload. For instance, BMCs 130 respectively associated with IHSs 110A-110N may provide the second multiple thermal attribute values associated with the multiple information handling systems to the cluster manager.

As one example, second multiple thermal attribute values associated with IHS 110A as IHS 110A executes the second workload may be represented via plot 340A (shown in FIG. 3B). As a second example, second multiple thermal attribute values associated with IHS 110B as IHS 110B executes the second workload may be represented via plot 340B (shown in FIG. 3C). As another example, second multiple thermal attributes associated with IHS 110C as IHS 110C executes the second workload may be represented via plot 340C (shown in FIG. 3D).

At 535, it may be determined that a thermal attribute value of the second multiple thermal attribute values exceeds a respective variance range of the multiple variance ranges as a first information handling system of the multiple information handling systems execute the second workload. In one example, the cluster manager may determine that a thermal attribute value of the second multiple thermal attribute values exceeds a respective variance range of the multiple variance ranges as a first information handling system of the multiple information handling systems executes the second workload. In a second example, a baseboard management controller of a first information handling system of the multiple information handling systems may determine that a thermal attribute value of the second multiple thermal attribute values exceeds a respective variance range of the multiple variance ranges as the first information handling system executes the second workload.

As an example, when a thermal attribute value of the second multiple thermal attribute values exceeds a respective variance range of the multiple variance ranges as the first information handling system executes the second workload, plot 340B may exceed allowable variance 330 (shown in FIG. 3C). For instance, plot 340B may exceed allowable variance 330 for period of time 350. As another example, when a thermal attribute value of the second multiple thermal attribute values exceeds a respective variance range of the multiple variance ranges as the first information handling system executes the second workload, plot 340C may exceed allowable variance 330 (illustrated in FIG. 3D). For instance, plot 340C may exceed allowable variance 330 for period of time 352.

In one or more embodiments, period of time 352 may not exceed a threshold of time to generate an alert. For example, plot 340C exceeding allowable variance 330 for period of time 352 may be an aberrant spike or an anomaly in executing a workload. In one or more embodiments, period of time 350 may exceed the threshold of time to generate an alert. For example, plot 340B exceeding allowable variance 330 for period of time 350 may not be an aberrant spike in executing a workload or may not be an anomaly in executing a workload.

At 540, an alert may be generated based at least on the thermal attribute value exceeding the respective variance range. In one example, the cluster manager may generate an alert based at least on the thermal attribute value exceeding the respective variance range. In another example, a baseboard management controller of the first information handling system may generate an alert based at least on the thermal attribute value exceeding the respective variance range. For instance, the baseboard management controller of the first information handling system may provide the alert to the cluster manager. In one or more embodiments, generating the alert based at least on the thermal attribute value exceeding the respective variance range may be performed in response to determining that the thermal attribute value of the second multiple thermal attribute values exceeds the respective variance range.

At 545, at least a portion of the second workload may be transferred from the first information handling system to a second information handling system of the multiple information handling systems. For example, the cluster manager may transfer at least a portion of the second workload from the first information handling system to a second information handling system of the multiple information handling systems. In one or more embodiments, transferring the at least the portion of the second workload from the first information handling system to the second information handling system may be performed in response to the alert.

In one or more embodiments, one or more of the method and/or process elements and/or one or more portions of a method and/or a process element may be performed in varying orders, may be repeated, or may be omitted. Furthermore, additional, supplementary, and/or duplicated method and/or process elements may be implemented, instantiated, and/or performed as desired, according to one or more embodiments. Moreover, one or more of system elements may be omitted and/or additional system elements may be added as desired, according to one or more embodiments.

In one or more embodiments, a memory medium may be and/or may include an article of manufacture. For example, the article of manufacture may include and/or may be a software product and/or a program product. For instance, the memory medium may be coded and/or encoded with processor-executable instructions in accordance with at least a portion of one or more flowcharts, at least a portion of one or more systems, at least a portion of one or more methods, and/or at least a portion of one or more processes described herein to produce the article of manufacture.
